The body of a kayaker who went missing over Labor Day weekend in Cypress Creek is believed to have been found by Texas Equusearch volunteers, according to that group's founder.

The body, believed to be Brian Conner, 42, was found Monday morning just before 7 a.m.

Harris County Precinct 4 chief deputy Mark Herman confirmed that medical examiners had retrieved the body from the scene after the Texas Equusearch team made the discovery.

Medical examiners are attempting to make a positive ID on the body, Herman said.

"Cypress Creek is very unforgiving and treacherous. Lots of logs, concrete, holes, and rebar," said Tim Miller, whose Equusearch group used SONAR equipment to locate the missing man.

Conner and his wife entered the water in Jesse Jones Park Saturday in separate kayaks for a scenic trip down Cypress Creek. But as the couple headed west along the creek and neared the Interstate 45 bridge, the woman realized her husband was no longer behind her, authorities said. She turned around and maneuvered back up the creek, where she found Conner's empty, overturned kayak. She spotted her husband, a Type I diabetic, clinging to a nearby branch. Authorities said the wife couldn't pull him from the rushing water or help him to the shore.

At one point, Miller says that as many as 18 volunteers were a part of the search for Conner, which began late Saturday. Conner's kayak had been recovered, but nothing else by Sunday evening. An additional crew stood watch overnight Sunday and early Monday in the hopes Conner would turn up.

Miller suspects that Conner had gone into diabetic shock around the time his kayak capsized in the rushing waters of Cypress Creek.
